image1 ve image2'deki her eşleşen bant çifti için birinci değerin ikinci değere bölünmesiyle elde edilen kalanı hesaplar. Resim1 veya resim2'de yalnızca 1 bant varsa bu bant, diğer resimdeki tüm bantlara karşı kullanılır. Görüntüler aynı sayıda banda sahipse ancak aynı adlara sahip değilse doğal sırayla çiftler halinde kullanılır. Çıkış bantları, iki girişten daha uzun olanın adına göre veya uzunlukları eşitse image1'in sırasına göre adlandırılır. Çıkış piksellerinin türü, giriş türlerinin birleşimidir.
